Itâ€™s called “CoGo” and is modeled after similar programs in other cities. Columbus officials call it a green and affordable way for visitors making short stops around downtown. Riders can sign up for an annual membership of $75, or rent and return a bike at any of the 30 downtown stations for $6 a day.

The program requires riders to wear a helmet and use arm signals when making turns.

Some downtown hotels say theyâ€™ll make free helmets available to guests, and at least two bike shops will offer customer discounts to CoGo members.
